![]() ![]() Update: Also, if you add Apple Watch support, there's another potential consideration. Store arrays and other data using Core Data, it's not as hard as they say. Only use NSUserDefaults for storing simple strings or booleans related to preferences. If you're learning how to code, learn the scalable way. I realized that if you're storing more than a few strings or booleans, NSUserDefaults really isn't ideal. Then I learned that retrieving an array isn't straight forward. ![]() NSUserDefaults is Also Limited in Functionįurther reading revealed how the read/write of NSUserDefaults really forces the app to read/write everything or nothing, all at once, so it isn't efficient. I spent hours trying to get type-errors to go away. However, I wanted to store a dictionary and, although possible, it was proving to be a pain. When I was implementing long term (after app close) data storage for the first time, everything I read online pointed me towards NSUserDefaults. ![]() ![]() If let stringTwo = defaults.stringForKey(įor anything more serious than minor config you should consider using a more robust persistent store: If let stringOne = defaults.stringForKey( Getting let defaults = NSUserDefaults.standardUserDefaults() Setting let defaults = NSUserDefaults.standardUserDefaults() In Swift 2.0 UserDefaults was called NSUserDefaults and the setters and getters were named slightly differently: Getting let defaults = UserDefaults.standard Setting let defaults = UserDefaults.standard UserDefaults lets us store objects against a key of our choice, It's a good idea to store these keys somewhere accessible so we can reuse them. The UserDefaults class provides convenience methods for accessing common types such as floats, doubles, integers, Boolean values, and URLs. The simplest solution for storing a few strings or common types is UserDefaults. ![]()
